It should have space before (. Some of the style in the old files may
not be correctly updated. :-( But when we introduce new code, we'd
better follow the rules

What you said should be included...
What's in my mind is checking the invariants in the EDF scheduling policy.
For example, at any time, the running VCPUs should have higher
priority than the VCPUs in runq;
At any time, the runq and replenish queue should be sorted based on EDF policy.

Dario, Jan and Wei, I almost finished a new version, but since this part is critical for the whole patch, let me summarize the feedbacks here. Please correct me if my understanding is wrong. 1) We don't need "guest_handle_is_null()" check, because null handle could be used in some special cases. And normally, handle is checked by copy_from(to)_guest* functions. 2) In domctl.h, add explain for nr_vcpus, because it is used in both IN and OUT ways. 3) Use printk(XENLOG_G_WARNING ...) here, because of its rate limit feature. 4) Do I still keep the spin_lock inside the loop body?

[Xen-devel] Scheduler/hypervisor traps, vm_event_vcpu_pause - some details on how they work?
Hey all, I'm trying to add a vm-event function that would execute just before a vCPU resumes execution. To do this, I need to know precisely how and when this happens. I've been browsing the codebase to try and gain some insight on the matter, but I still need some clarifications as parts of it are not so straight-forward. Currently my understanding is that a vCPU can be entered in 3 ways: 1) The first entry, when the vCPU is first created. On ARM, the PC of the vCPU is set to continue_new_vcpu. Q1. How does this happen on X86? 2) After a hypervisor trap (X86 VMENTER/ARM ERET). Q2. How does pausing of the current vCPU (vm_event_vcpu_pause) work, specifically where does the context switch to another vCPU happen? Is it reentered through the below mentioned scheduling functions? Q3. Can we resume on another vCPU than the one that trapped if it wasn't paused? Q4. Can a hypervisor trap be interrupted by a scheduling operation? 3) Scheduler interrupt -> functions context_switch/continue_running. Q5. Are these 3 the only ways a vCPU can be entered? Thank you very much, Corneliu. ___ Xen-devel mailing list Xen-devel@lists.xen.org http://lists.xen.org/xen-devel
